1 Ch me 4 D aw g F sw nor WATER TANK HEATER This invention is related tomobile hot water heaters. More specifically, this device consists of asmall tank placed under the hood of a vehicle enabling the smalltrailer, boat operator, etc., to have a supply of hot water for washing,showering, etc., whenever desired. The device is particularly useful forsmall camping units that are used on pickup trucks. It is also a muchsafer method of heating hot water in small boats because the danger ofexplosion with heaters heated with the conventional propane is notpresent with the elimination of propane.

The primary object of this invention is to provide a simple andefficient mobile hot water tank. 4

Another object of this invention is to provide a safe means ofdelivering hot water in a mobile vehicle.

The above and other objects of this invention will become apparent tothose skilled in the art after a consideration of the following detaileddescription of the preferred embodiment of this invention taken togetherwith the accompanying drawing in which:

FIG. 1 is a cutaway elevational view of the tank;

FIG. 2 is a sectional view taken on line 2--2 of FIG. 1;

FIG. 3 is a sectional view taken on line 33 of FIG. 1; and

FIG. 4 is a diagrammatic view of water flow through the hot watersystem. Referring in detail to the drawing, there is illustrated a freshwater tank having a fill cap 12, pressure gauge 14, relief valve 13, andair stem at the top of tank 10. Mounted at the center of tank 10 alongthe longitudinal axis thereof is a cylindrical passageway 16 having bothends thereof connected to water line 18 at the opposite ends of tank 10.

FIG. 4 shows water flowing out of a conventional radiator 20 and beingpumped through the engine along line 18 into passageway 16 by an enginewater pump (not shown). The flow of radiator water is controlled by theheater control inside the vehicle, the vehicle heater and defroster 22being positioned in line 18 on the exit side of passageway 16. Tank 10is stored with fresh water which is heated as the heated water from theengine passes through passageway 16. A pump 24, which may be actuatedmanually, by air pressure, or by electrical mechanical means draws theheated fresh water from tank 10 for use. It should be noted that as theradiator water circulates through tank 10, it takes approximately a mere10 minutes to heat the entire body of fresh water in tank 10.

While the preferred embodiments of this invention have been illustratedand described, it will be understood by those skilled in the art thatmodifications and changes may be resorted to without departing from thespirit and scope of the invention.

I claim:

1. A mobile fresh water heater, comprising a generally horizontal freshwater storage tank, a generally horizontal cylindrical passagewaymounted at the center of the tank along the longitudinal axis of thetank between opposite ends of the tank in a manner so that water in thetank is sealed off from the inside of the passageway, the passagewaybeing part of an internal combustion engine cooling system water line,the flow of engine heated water through the passageway causing the freshwater in the tank to heat up, a fill cap at the top of the tank forpouring in fresh water, a pressure gauge and release valve with an airstem extending from the top of the tank, a water pipe extending downwardfrom the bottom of the tank, and a pump connected to the pipe forpumping the heated fresh water to the area where the water is to be usedfor washing and consumption, said passageway having a diameter largerthan that of the water line located outside the tank for increasing thearea of heat exchange with said passageway positioned to receive theflow of water directly after the water leaves the engine of the mobilevehicle.
